That ‘patch’ of light is M13, the Great Globular Cluster

In 1716, English astronomer Edmond Halley noted, “This is but a little Patch, but it shews itself to the naked Eye, when the Sky is serene and the Moon absent.” Of course, M13 is now modestly recognized as the Great Globular Cluster in Hercules, one of the brightest globular star clusters in the northern sky.

Dust clouds now, stars later

Dust clouds now, stars later

Situated in rich star fields and glowing hydrogen gas, these opaque clouds of interstellar dust and gas are so large they might be able to form stars. Their home is known as IC 2944, a bright stellar nursery located about 5,900 light years away toward the constellation of Centaurus. The largest of these dark globules, […]

‘Supernova in a jar’ offers peek inside star death

Image credit NASA, Caltech, MPIA, and Calar Alto Tycho’s supernova remnant, a real-world example of a Type Ia supernova. An an attempt to peer inside powerful star explosions, scientists recently made a “supernova in a jar” using a chemical reaction in a viscous fluid. Called the iodate-arsenous acid (IAA) system, the experiment involved injecting a […]

Astronomers still wondering about the ‘Star of Wonder’

Astronomers have proposed a variety of sources over the years for the Christmas star — comets, a supernova or a grouping of planets. The actual astronomical events of the time suggest a solution, according to Griffith Observatory astronomer John Mosley. Mosley’s 1987 book “The Christmas Star” examines the sky during the time frame that historians […]
